Ratfolk

Ratfolk are small, rodent-like humanoids; originally native to subterranean areas in dry deserts and plains, they are now more often found in nomadic trading caravans. Much like the pack rats they resemble, ratfolk are tinkerers and hoarders by nature, and as a whole are masters of commerce, especially when it comes to acquiring and repairing mechanical or magical devices. Though some are shrewd merchants who carefully navigate the shifting alliances of black markets and bazaars, many ratfolk love their stockpiles of interesting items far more than money, and would rather trade for more such prizes to add to their hoards over mere coins. It’s common to see a successful crew of ratfolk traders rolling out of town with an even larger bundle than they entered with, the whole mess piled precariously high on a cart drawn by giant rats.
